Drop in your dry stems. Mixstering mixes the song — you never touch a fader.

MIX ONLY · NO MASTERING BUNDLED
STEP 1

Pick the genre

The genre decides how Mixstering hears your song — how hard the drums hit, where the vocal sits, how much room is in the mix. An orchestra session and a hip-hop record never get the same ears.

DYNAMICS

Pick the dynamics

Every genre gets two dynamics — two ways its loud and quiet moments are treated when Mixstering mixes. The first one is already picked, so nothing blocks you; switch any time before you mix.

STEP 2

Add your dry stems

The stem rule — read this before you export

  • Dry, no effects. Export every stem with no reverb, no EQ, no compression — nothing on it. Mixstering adds all of that.
  • Every stem starts at the same place. All stems must begin at bar one of the song, so they line up when played together.
  • Full length, silence included. A vocal that only sings in the chorus still gets exported as a full-length stem with the empty space in it. Never upload loose pieces — a chorus clip on its own will land in the wrong place.
Drop stem files here, or tap to browse WAV, AIFF, MP3, M4A, FLAC, OGG — as many stems as your song has. Files stay on your device; the mixing happens right here.

No stems yet. Mixstering sorts each stem by its file name — vocals, drums, bass, keys, guitar, strings — and you can correct any stem's type after it loads.

Mixing comes later, on purpose: once your stems line up here, Step 3's vocal tuning is already set to Natural Tune by default — the “Mix my song” button lives in Step 4, with the player it feeds.

STEP 3

Vocal tuning

Tuning runs first in the vocal chain — before the vocal EQ, compression and reverb — on every stem marked Vocals. It works the way the studio tuners do: Mixstering finds each note you sang, measures where that note's centre sits, and moves the whole note by one steady amount — so your vibrato and slides stay yours instead of being flattened and wobbled, and breaths, consonants and “s” sounds are never tuned at all, which is where the scratchy, shaky sound used to come from. A note that's already in tune is left as the original recording. You don't need to know the key: as soon as your stems land in Step 2, Mixstering detects two keys separately — the song key from all your stems together, and the vocal key from your Vocals stems alone, the notes you actually sang. They aren't always the same, so both are shown below. Tuning follows the vocal key by default, so Natural Tune works even if you never touch a key picker. Natural Tune is already picked for you below — you don't have to tap anything to move on to Step 4. Tap No Tuning or Hard Tune only if you want something different.

Your keys — song key and vocal key

Detected automatically when you upload your stems. The song key hears the whole track; the vocal key hears only the singing. If either one looks wrong, fix it with its picker — your pick replaces the detected key for that one only.

SONG KEY From all stems together — the track the vocal sits on. —

Add your stems in Step 2 and Mixstering will detect the song key.

VOCAL KEY From your Vocals stems alone — the notes actually sung. —

Add a Vocals stem in Step 2 and Mixstering will detect the vocal key from the singing alone.

STEP 4

Hear the default mix

This is the straight studio mix — the default Mixstering mix for your genre, before any tone choice. Press “Mix my song” and Mixstering renders it with the vocal tuning from Step 3 — style and key, Natural Tune unless you changed it — applied first in the vocal chain, so the sample you hear is the tuned vocal, exactly as it will be in the saved mix. You get a 45-second sample first — long enough to get past the intro and actually hear the vocal in the mix, the way you'd hear a reference in the studio. Hear this default mix to unlock the tones in Step 5 — the full song unlocks when you save your Mixed in Tone version there.

What “industry standard” means here, in numbers: the vocal is balanced on top of the track and de-boxed — a −3.8 dB cut at 420 Hz, right in the 300–500 Hz range that makes a voice sound like it's singing through a cardboard box — with presence lifted at 4.5 kHz so the words stay clear, and the finished mix is peak-held to about −0.7 dB so nothing clips at 0.0. Loudness is not baked into the mix: that is mastering's job, kept separate in Step 7 — Streaming masters at about −14 LUFS, Loud share at about −8 to −9 LUFS, both under a −1.0 dB true-peak ceiling.
Add at least two stems in Step 2 to mix.
0:00 / 0:00 45-SECOND SAMPLE

🔒 Nothing to hear yet. Add your stems in Step 2, then press “Mix my song” — Natural Tune is on by default in Step 3, and your tuned 45-second sample appears right here.

STEP 5

Mixed in Tone

Heard the default? Now pick your tone, then press Mixed in Tone — Mixstering renders your mix in that tone. Hear the mixed-in-tone version in the player that appears, and only then save and download it below.

Your stems, genre, dynamics, tuning or key changed — mix again to hear the current song.

Hear the default mix in Step 4 first — tones unlock once you've heard it.

0:00 / 0:00 45-SECOND SAMPLE

🔒 Nothing to hear here yet. Pick a tone above and press “Mixed in Tone” — the version in that tone appears right here for you to hear before you save anything.

STEP 6

Save and download

Below the player, once you've heard it: save and download the full-length mixed-in-tone mix as a WAV — the whole song, not just the 45-second sample — and sit with it for as long as you want, before mastering is even mentioned. Mix only — no mastering is applied.

Press “Mixed in Tone” and hear the version above first — then save and download it here.
STEP 7

Mastering — a separate step

Mastering is not part of the mix and never gets bundled into it. When — and only when — you've lived with your saved mix and you're ready, come here and master it as its own decision. Six flavors run dark to bright — Basement to Air — with big steps between them, and Mixstering measures your saved mix first, then sets the EQ and compression for this song inside the flavor you pick. This is the end stage, so the preview here is the whole song — not a sample — you hear the full master end to end before you save it, then download that same full master as a WAV or an MP3. The earlier steps stay short samples on purpose; the full song is only given up here, at the end.

Locked for now. Save a mix in Step 6 and this section opens — mastering starts from your saved mix, never straight from the stems.

Export loudness

Where is this master going? Pick the loudness at export — streaming platforms play everything back at their own level, while a loud share keeps full strength for apps and direct sharing. The true-peak ceiling is −1.0 dB either way.

Hear your master — the whole song

This player is not a sample. Press play and it plays the full master from start to finish — the whole song, exactly as it will download below as a WAV or an MP3.
